STEAM-VULCANIZER.

Specification of Letters Patent.

Application filed August 28, 1916. Serial No. 117,125.

To all whom it may concern:

Be it known that I, JOSEPH MATHE, citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and use ful Improvements in Steam-Vulcanizers, of which the following is a specification.

This invention relates to an im rovement in steam vulcanizers of the class a apted for use in reforming or repairing outer or inner rubber vehicle tires, and has for its object, broadly, to provide an apparatus for this purpose which will be convenient in use for applying heat, coincidently, to rubber tires of. various diameters, the parts to be few and simple so that manufacture will be economical, and so arranged that the work of vulcanizingmay be performed conveniently.

The inventionincludes the combination with a boiler for producing steam, of a vulcanizing receptacle having continuous, outer and inner concavo-convexed walls to provide an upright, annular container in which the rubber tires may be deposited for the purpose of' bein heated, said container being provided ad] acent to its outer and inner sides and bottom with a concavo-convex casing to form, in cross-section, an intermediate steam chamber of substantially U-shape, lids or covers of segmental form being provided for the heating chamber and arranged to swing outwardly, and an apertured, horizontal, annular partition being provided for supporting the tires in the chamber and being movable for conveniently removing said when heated, steam being admitted to the upper part at one of the sides of the U- shaped chamber, and a discharge port for condensed steam being provided for said chamber to communicate with the boiler, said discharge port being disposed at the bottom and at substantially 180 degrees from the intake of the chamber tending to cause uniform circulation of the heat or steam.

The invention consists of the novel construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accompanymg draw- 0 ing, it being understood that changes in form, size, proportion and minor details may be made in accordance with the appended claims without departing from the spirit of the invention or sacrificing any of its advantages.

In the drawing, Figure 1 is a side view of the apparatus, the boiler being partly broken away and the vulcanizing receptacle being in vertical section. Fig. 2 1s a plan view of the vulcanizing receptacle, the lids being swung to an open position. Figs. 3 and 4 are enlarged detail Views tov clearly illustrate construction, Fig. 3 being a sectional view showmg a fastening means for connecting the segmental lids to the inner wall of the U- shaped chamber, and Fig. 4 being a side View of the same. Fig. 5 is a transverse section through the vulcanizing receptacle and steam chamber on line 55 of Fig. 1, the tires and apertured partition being removed. Fig. 6 is a plan view of the apertured, annular partition. Fig. 7 is a sectional view of the partition on line 77 of Fig. 6. Fig. 8 illustrates a grip-rod used for removing the annular supporting plate or partition from the heating chamber.

Referring now to the drawing for a more particular description, numeral 8 indicates a. contlnuous wall of U-shape in cross-section to provide an annular container 9 in which the rubber tires 10 may be deposited, a similar wall 11 of greater dimensions being provided and disposed outwardly and ad]acent to wall 8 to provide, intermediately, an annular heating chamber 12, a plurality of inwardly pro ecting spacing-lugs 13 being provided for the wall 11 below its top; and the upper end of said wall 11, at its respectlve outer and inner sides is provided with lnwardly projecting, annular, horizontal flanges 14 and 14.

As thus describ d, the walls 8 and 11 may be maintained parallel and in spaced relatlon, so that the outer and inner parts of chamber 12 may be of substantially uniform width, each of the walls 8 and 11 being transversely curved at their bottoms, as best shown in Fig. 1, and as indicated at a.

Numerals 15 indicate lids arranged to cover the container .9, each lid having a lids, when closed, facilitating in providing Patented Mar. 6, 1911'.

may bev f placed in the container 9, the form of the" a required space, said container being of such width that several tiresof various diameters may be simultaneously heated.

At 19 is indicated a steam boiler, preferably heated by means of a gas burner 20. It is provided with a pipe 21 communicating with the annular'chamber 12 near the top of wall 11, and is provided with a return pipe 22 communicating with the bottom of chambr -12. Pipe 22 communicates with a hollow casing 23 used as a mold for repairing tires, and a pipe 24 communicates with the hollow casing 23 and with the boiler, preferably near the bottom of said boiler. Numeral 25 indicates a valve to control a movement of steam from the casing 23 to the boiler through a pipe 26, and numeral 27 indicatesa blow oil valve for the boiler; and by regulating this valve 27 the certain degree of steam pressure or heat best adapted for vulcanizing may be maintained, this dogrce of heat being indicated by a thermometer 28.

Numeral 29 indicates an annular supporting-plate or partition. having hooks 30 projccting from its upper side and provided with numerous apertures 31. It is adapted to be seated in engagement with wall 8, near the curved part a of said wall, in the container 9. in operation, the lids being swung to an open position, and resting upon ledges 82 with which the outer part of the wall 11 is provided, the tires are placed in the container. The lids are then closed and are secured. by means of latches 33 which are pivotally mounted in the staples 3a with which the inner part of wall 11 is provided, said latches engaging the catches 35 of the flanges 17 of said lids. Steam under control of valve 36 then passes through pipe 21 to enter the heating chamber, an adequate degree of heat being employed for vulcanizing, and the steam, more or less condensed, will return to the boiler through pipes 22 and 24 and the intermediate casing 23.

It will be understood that the tires, after being heated, will be in. a condition more or less plastic, and care should be exercised so that their removal from the container will not be attended with injury. After the lids have'been swung outwardly, all of the tires may be elevated and removed without injury, the annular plate or partition 29 being moved upwardly by any suitable means, the means herein shownbeing gripping-bars 37 having loops which are adapted to engage the hoolrs 30 of said {J ate.

By referring to Figs. 1 and 6 it will be seen that the apertures 31 of the plate 29 permit the heat to circulate or move upwardly from the curved bottom of the easing 8 for heating the tires.

ince the lids 15 are arranged to swing neisaoo outwardly to an open position, as best shown in Fig. 2, an operator may have convenient access to the chamber 9 for depositing the tires therein or for removing the annular plate 29 together with the tires. Also since the lids are supported by the ledges-32, when swung outwardly, the work will be facilitated in the matter of opening or making a closure of the container 9.

Having fully described the construction what I claim as my invention and desire to secure by Letters Patent is,-

1. In combination with an upright, endless casing of U-shape in cross-section, a second upright, endless casing of U-shape in cross-section provided at its top with opposed, inwardly projecting flanges, said second casing being disposed outwardly of and adjacent to the first named casing, flanges engaging the sides at the top of said first named casing to provide an annular chamber below the flanges intermediate casings, means for heating said annular chamber, and a plurality of lids of segmental form each having a hingeable connection with the second casing and adapted to make a closure of a part of the first named casing.
